Frame-Relay Multipoint

[anuarsuh4rty]

Anyone can help me?

Encountered problem in configuring frame relay multipoint.

Status 0x0.

All the router not connected. When do ping result is host unreachable.

Configuration in Router HQ >>

1. int Fa0/0: 192.168.0.78/29

2. int Serial0/0

    encapsulation frame-relay

    no shut

3. int Serial0/0.1 multipoint

    ip add 10.0.0.167 255.255.255.252

Hello

Your hub router ip range isnt large enough accomodate the spokes also if you use point-to-point on the spokes

no  need to use the broadcast keyword

Hub router

interface Serial0/0

no ip address
encapsulation frame-relay
no shut

int Serial0/0.1 multipoint

ip add 10.0.0.167 255.255.255.0

rame-relay map ip 10.0.0.5 102

frame relay map ip 10.0.0.9 103

frame relay map ip 10.0.0.13 104

Spoke router5

Hello Khairul,

I understand that you are trying to configure a Frame-Relay Multipoint Topology with hosts on every spoke site be able to communicate with the Hub as well other spokes.

Basically, the IP address assignment for the WAN interfaces was wrong. Since, this is a multi-point topology, all the sites (Spokes and Hub) will be part of the same subnet.

For your understanding, I have re-created the same topology in GNS and below, you can find the topology with complete configurations.

Hope your queries were answered

Hello Mithun

I have noticed in your config. Your mapping for spoke to spoke routers has broadcast keyword enabled,this should not be the case as it can cause unnecessary redundant routing traffic towards the hub router.
